Make rolodex country code optional for Award printing.

fixes rSmart/issues#448

So I don't believe that blank country codes for rolodex entries should be a problem. In this service they attempted to allow it, although missed the mark. So null country codes were allowed in half the cases, but blank country codes weren't allowed at all. This PR instead of fixing the validation message simply allows the country code to be blank and doesn't include that data in the report if it is blank.
